Web Service Example
HTTP web service with automatic service discovery and registration.
What It Does
This example creates an HTTP service that:
- Serves RESTful API endpoints
- Registers with service discovery
- Provides health checks
- Uses standard Go HTTP handlers
Run It
go run main.go
Test It
# Get service info
curl http://localhost:9090/
# List all users
curl http://localhost:9090/users
# Get specific user
curl http://localhost:9090/users/1
# Health check
curl http://localhost:9090/health
Key Features
- Standard HTTP: Use familiar
http.Handlerinterface - Service Discovery: Automatically registers with registry
- Health Checks: Built-in health endpoint
- JSON APIs: Easy REST API development
When to Use
Use web.Service when:
- Building REST APIs
- Serving web UIs
- Working with HTTP-specific features
- Migrating existing HTTP services
Use regular micro.Service when:
- Building RPC services
- Need bidirectional streaming
- Want automatic load balancing
- Prefer structured RPC over HTTP
